Read Word 9 00…07 Underrange bits – these bits are set if the input signal is below the input
channel’s minimum range.
08 …15 (10…17) Overrrange bits – these bits are set if 1), the input signal is above the
input channel’s maximum range, or 2), an open detector is detected.
Read Word 10 00…01 Not used – set to 0
02 Reserved
03 Power Up bit – this bit is set (1) until configuration data is received by the
module.
04…06 Critical Error bits – If these bits are anything other than all zeroes, return
the module to the factory for repair.
07 Unused – set to 0
08 (10) Calibration Out of Range bit – set to 1 if a reference signal is out of
range during calibration.
09 (11) Calibration Done bit – set to 1 after an initiated calibration cycle is
